Which aspect is crucial for ensuring that high-visibility clothing is effective?

The effectiveness of high-visibility clothing primarily relies on its ability to make the wearer easily seen, especially in environments where visibility may be compromised, such as construction sites or roadwork. High-visibility clothing typically incorporates reflective materials that enhance the wearer's visibility in various lighting conditions, including low light or nighttime. The reflective properties ensure that light from vehicles or other sources bounces off the clothing, alerting others to the presence of workers on site.

By using materials that reflect light, the safety of personnel can be significantly increased, reducing the risk of accidents. Thus, the inclusion of reflective components is essential to meet safety standards and effectively protect workers in hazardous environments.
